You often read of slaves that have no limits and no safeword, but in essence I have both. As I wrote last time, Master takes care of my limits (though these were negotiated). I do have a safeword, but have never used it.
In both of my BDSM relationships we have used the traffic light system. Green when everything is good. During a scene it is important for the dominant partner to check in regularly that all is well. There might be occasions when the sub can’t speak (if gagged or in subspace) and so is unable to say the word. So non-verbal communication is vital. I’ve found it is perfectly easy to communicate green (or another colour to Master even if gagged, by nodding, eye contact or some kind of hand signal.
Amber often denotes some kind of limit is being reached. Perhaps the pain is becoming intense or restraint uncomfortable. Sometimes an adustment is needed but other times it is time to push the limit a little. Again, eye contact, verbal and non verbal communication helps identify when it is ok to continue and when things should stop. I called yellow recently (though didn’t actually say the word yellow) when tied to a St Andrew’s cross.
My right arm doesn’t have the same range of movement it did before my mastectomy. I wanted to try it but found that after a few minutes I had to ask to be untied. Because we know each other well and Master was attentive we reached my limit and he untied me. This has just made me want to get that arm more supple so it is ok to be tied in that way in the future.
Red is my safeword. I have never actually used it as I have never felt the need. However, I would and being Master’s slave wouldn’t stop me. It is testament to him that we have never needed to move past amber or me asking for a break. He is respectful of my needs and always keeps a close eye on how I am doing.
Perhaps I don’t really need a safe word? But if I ever felt I did it is there.
